Unfortunately I have to agree with Eck......
There is no place in this country to build a home of any type that is safe from mother nature. There is no state that has never had a tornado, the USA has more tornadoes than the rest of the world combined. The USA averages 1,000 per year, Canada is a distant second averaging "only" 100 per year. Some of that may simply be the better reporting than any other country?
I guess we need to move everyone off of the west coast because they have earth quakes and volcanoes, we need to move everyone out of the middle of the country because of the tornadoes, and we need to get everyone out of the south and east coast to protect them from hurricanes. Look out Mexico and Canada, here we come.
Even a poured concrete home rated for 300MPH wind is not safe, tornadoes have been clocked at over 300 MPH. Will that concrete home still stop a 2,000 lb car that the wind picked up that is coming in at 300 mph? How about a 5 ton oak tree?
I do agree that a mobile home is less safe than a well built home. A near miss will leave the well built home standing with some damage but that same near miss could still totally wipe out a mobile home.
Yes there are some areas that are very prone to natural disasters and should not have any buildings located there. Like places along a river that flood every couple of years. I did speak to one person that lives in a flood prone area. They look at it as they get all new stuff every couple of years almost for free cuz I'm paying for it. The inconviniance is worth it to always have new stuff.
